DISTILLING-COLUM To all whom it may concern:

Be it known that I, FRANZ PAMPE, a subjcct of the German Emperor,residing at I-Ialleon-the-Saale, Kingdom of Prussia, Germany, haveinvented certain new and useful Improvements in Distilling-Columns; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appert-ains to make and use the same, reference beinghad to Lhe accompanying drawings, and to letters or figures of referencemarked thereon, which 'torm a part of this specification.

The present invention relates to distillation and rectification columns.

That the same may work well it is necessary, on the one hand, that thevapor have the necessary velocity for atomizing the liquid, and, on theother hand, that the liquid be not dammed back or unduly retarded in itsflow, in consequence of the vapor having too great a velocity.

An important object of the present invention is a substantialimprovement in the .construction of distilling columns by simplifyingthe same in such a manner that even when there is a considerablevariation in the quantity of vapor flowing through the apparatus it isimpossible for the liquid to be dammed back or prevented from flowingthrough the column, and moreover, that the rectifying action isconsiderably increased.

In order that the invention may be clearly understood, reference is madeto the accompanying drawing, in which one embodiment is represented byway of example.

In said drawing -Figure 1 is a vertical section through so much of acolumn as is necessary for an understanding of the invention. 2 is aplan of the same.

The column comprises a casing, preferably cylindrical, to the interiorof which are connected the annular concave plates Z) by means of theirupturned outer flanges j, that is, these plates are inclined downwardlyfrom said flanges toward their center.

These plates are perforated, as shown at c and have an inner, downwardlyturned scr Specification of Letters Patent. Application filed January 3,1908.

g pass near their inner flange and carry spacing sleeves it betweenwhich are held the perforated, conical or convex plates 0 also having adownwardly turned serrated flange 2", that is, these plates 0 areinclined downwardly from their centers toward their edges.

The increased rectifying action hereinabove referred to is obtained bythe lower conical plates 0 being provided with perforations c in theirannular faces (Fig. 2) in such manner that, firstly, a current of vaporfrom b atomizes the liquid which drops down from the points of thenotches d and the drops of liquid fall onto the plates 0, and, secondly,that the vapor passes from below the convex or conical plates 0 throu hthe perforations e in thesame. The liquid flows over and through theplates 0, and thus two jets of vapor move through the liquidapproximately at right angles to one another, and an increasedcontacting action is obtained between the vapor and the liquid. \Vhat Iclaim as my invention and desire to secure by Letters Patent is Adistilling column comprising in combination, a vertical cylindricalcasing, annular, vertically spaced, perforated plates having upwardlydirected flanges at their outer periphery secured to the casing, anddownwardly directed serrated flanges at their inner periphery, saidplates inclined downwardly toward their center, perforated plates,smaller than, spaced from, alternating and concentric with theaforementioned plates, whose surfaces incline downwardly from theircenters and have depending serra ted flanges at their outer edges, saidplates dimensioned to locate their flanges between the inner and outerperipheries of the annular plates and means to maintain the plates intheir relative spaced positions.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

FRANZ PAMPE.
